摘　　要：旧路改造工程中,为充分利用已有老路,需要在老路的基础上进行拓宽扩容。如何确保拼接段新路堤的稳定性,是新老路基拼接设计与施工中要解决的首要问题。文章对205国道和245省道宿迁段拼接施工过程中拼接与现场监测的情况进行了总结分析,供设计与施工单位在公路拼接工程中参考。In order to make full use of the existing road in the old road reconstruction project, it needs expansion construction on the basis of the existing road. So how to ensure the stability of the new embankment splicing section is the primary problem to be solved in splicing design and construction of the new and old subgrade. This paper summarizes and analyzes splicing construction and field monitoring ,during the splicing construction of the Snqian section of 205 national highway and 245 provincial highway. It can be taken as reference for similar splicing construction projects.
